Plone TypeError: 'NoneType' object does not support item assignment

Good evening, Plone community!

I am in the process of getting my plone instance working. Unfortunately, when I go to create a new site, there is an error. The traceback is below. Note: I can't provide the whole traceback due to the post limit.
